If you're not that tall (for a girl it's always hard...), you shud make sure that you stand next to the most drunken idiots. It's quite easy to push foward, you only have to wait til they topple down. And that happens very fast... In the beginning of one concert, I stood in row 10 or 12 and in the end of the first song, I stood directly in front of the stage. If you manage this, do me a favour and say hello to Dave Grohl.
